Nortrak can supply guard rails in standard AREMA tee rail configurations in addition to the Nortrak designed Vanguard system. The Nortrak Vanguard system is available for use in heavy haul and transit systems. The Vanguard system utilizes a European rail section designed specifically for use in guardrail assemblies. Bolted and bolt-less designs are available - the latter, patented design, allows for easy adjustment to suit variable tie spacing and minimizes maintenance by eliminating bolts. Both systems allow flangeway width adjustments and individual part replacement.
